MICROFLUIDIC DEVICE AND MICROFLUIDIC APPARATUS USING THE SAME
First Claim
1. A microfluidic device, comprising:
- a substrate;
a flow channel disposed in the substrate for flowing through fluid therein;
a first resistive element for primarily heating the fluid in the flow channel; and
a second resistive element for supplementarily heating the fluid in the flow channel, the second resistive element being disposed at a position different from a position where the first resistive element is disposed.

Abstract
To improve temperature distribution of fluid in a flow channel of a microfluidic device in which a resistive element disposed in substrate as that in which the channel is formed is heated to control the temperature in accordance with resistance of the element, provided is a microfluidic device including: a substrate; a flow channel disposed in the substrate for flowing through fluid therein; a first resistive element for primarily heating the fluid; and multiple second resistive elements for supplementarily heating the fluid, the elements being disposed at positions different from position where the first element is disposed. A microfluidic apparatus operating the device stores a relational expression between a temperature of the fluid and resistance of the first element, and a fixed value of a ratio between a heat energy input into the first and second element, and controls the temperature in accordance with the expression and the value.

3. A microfluidic device, comprising:
-
a substrate; multiple flow channels disposed in parallel to one another in the substrate for flowing through fluid therein; first resistive elements for primarily heating the fluid in the multiple flow channels, the first resistive elements being disposed independent from one another so as to correspond to the number of the multiple flow channels; and a second resistive element for supplementarily heating the fluid in the multiple flow channels, the second resistive element being electrically independent from the first resistive elements and disposed in a region of the substrate exterior to an outermost first resistive element in the substrate among the first resistive elements. - View Dependent Claims (13)
